No magic length, +though, so if you change that it won't automatically prune or add +empty spots. + +### Yallist.create(..) + +Alias for Yallist function. Some people like factories. + +#### yallist.head + +The first node in the list + +#### yallist.tail + +The last node in the list + +#### yallist.length + +The number of nodes in the list. (Change this at your peril. It is +not magic like Array length.) + +#### yallist.toArray() + +Convert the list to an array. + +#### yallist.forEach(fn, [thisp]) + +Call a function on each item in the list. + +#### yallist.forEachReverse(fn, [thisp]) + +Call a function on each item in the list, in reverse order. + +#### yallist.get(n) + +Get the data at position `n` in the list. If you use this a lot, +probably better off just using an Array. + +#### yallist.getReverse(n) + +Get the data at position `n`, counting from the tail. + +#### yallist.map(fn, thisp) + +Create a new Yallist with the result of calling the function on each +item. + +#### yallist.mapReverse(fn, thisp) + +Same as `map`, but in reverse. + +#### yallist.pop() + +Get the data from the list tail, and remove the tail from the list. + +#### yallist.push(item, ...) + +Insert one or more items to the tail of the list. + +#### yallist.reduce(fn, initialValue) + +Like Array.reduce. + +#### yallist.reduceReverse + +Like Array.reduce, but in reverse. + +#### yallist.reverse + +Reverse the list in place. + +#### yallist.shift() + +Get the data from the list head, and remove the head from the list. + +#### yallist.slice([from], [to]) + +Just like Array.slice, but returns a new Yallist. + +#### yallist.sliceReverse([from], [to]) + +Just like yallist.slice, but the result is returned in reverse. + +#### yallist.toArray() + +Create an array representation of the list. + +#### yallist.toArrayReverse() + +Create a reversed array representation of the list. + +#### yallist.unshift(item, ...) + +Insert one or more items to the head of the list. + +#### yallist.unshiftNode(node) + +Move a Node object to the front of the list.
